Asteroid 16 Psyche might not be what scientists expected

The widely studied metallic asteroid known as 16 Psyche was long thought to be the exposed iron core of a small planet that failed to form during the earliest days of the solar system. But new University of Arizona-led research suggests that the asteroid might not be as metallic or dense as once thought, and hints at a much different origin story.

First-ever nationwide mammal survey published

How are the squirrels doing this year? The bears? The armadilloes? How would you know? A new paper published June 8 sets up the framework for answering these questions across the United States by releasing the data from the first national mammal survey made up of 1,509 motion-activated camera traps from 110 sites located across all 50 states.

Normal breathing sends saliva droplets 7 feet; masks shorten this

The World Health Organization and the Centers for Disease Control recommend keeping a certain distance between people to prevent the spread of COVID-19. These social distancing recommendations are estimated from a variety of studies, but further research about the precise mechanism of virus transport from one person to another is still needed.

X-ray scanner spots cancers and analyzes drugs in minutes

Engineers at Duke University have demonstrated a prototype X-ray scanning machine that reveals not just the shape of an object but its molecular composition. With unprecedented resolution and accuracy, the technology could revolutionize a wide range of fields such as cancer surgery, pathology, drug inspection and geology.

Panama expands the limits of the Coiba protected area

On June 8, World Oceans Day, the President of Panama, Laurentino Cortizo, signed an executive decree that expands the limits of the Cordillera de Coiba protected area, a step that will double the amount of Panamanian marine surface that is under some degree of protection. The scientific basis for this initiative was a multidisciplinary effort led by marine biologist Hector M. Guzman, from the...

NASA's Roman Space Telescope selects 24 flight-quality heat-vision 'eyes'

NASA's Nancy Grace Roman Space Telescope team recently flight-certified all 24 of the detectors the mission needs. When Roman launches in the mid-2020s, these devices will convert starlight into electrical signals, which will then be decoded into 300-megapixel images of large patches of the sky. These images will allow astronomers to explore a vast array of celestial objects and phenomena,...

The next Venus missions will tell us about habitable worlds elsewhere

When the DAVINCI+ and VERITAS missions to Venus were given the green light by NASA last week, the scientific community was stunned. Most had expected that NASA, which hadn’t launched a dedicated mission to Venus in 30 years, would be sending at least one mission to the second planet from the sun by the end of the decade. Two missions, however, blew everyone’s mind.  Maybe NASA...

Solar Eclipse - June 10, 2021

Rapamycin changes the way our DNA is stored

Our genetic material is stored in our cells in a specific way to make the meter-long DNA molecule fit into the tiny cell nucleus of each body cell. An international team of researchers at the Max Planck Institute for Biology of Aging, the CECAD Cluster of Excellence in Aging Research at the University of Cologne, the University College London and the University of Michigan have now been able to...

An atomic look at lithium-rich batteries

An international team of collaborators has made the first direct observation of the anionic redox reaction in a lithium-rich battery material. The research opens up pathways for improving existing battery cathodes--and designing new ones.

SARS-CoV-2 protease cuts human proteins; Possible link to COVID-19 symptoms

The SARS-CoV-2 papain-like protease (PLpro) plays an essential role in processing viral proteins needed for replication. In addition, the enzyme can cut and inactivate some human proteins important for an immune response. Now, researchers have found other targets of PLpro in the human proteome, including proteins involved in cardiovascular function, blood clotting and inflammation, suggesting a...

How catalysts age

Researchers have developed a new tomography method with which they can measure chemical properties inside catalyst materials in 3-D extremely precisely and faster than before. The application is equally important for science and industry.

Skeletons of Viking men to be reunited in Danish exhibition

DNA tests on ancient bones show men were related and died following violent incidentsThe skeletons of two Viking age men who were related but died on opposite sides of the North Sea are to be reunited in an exhibition in Copenhagen this month.DNA tests on the ancient bones suggest the men were either half-brothers or a nephew and an uncle, according to Prof Eske Willerslev, a Danish evolutionary...
